To all whom it may concern:

Be it known that we, NORMAN H. BEEBE and WILLIAM A. THOMAS, citizens of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Threshing-Harvesters, of

which the following is a specification.

This invention relates to an lmprovement in threshing harvesters for harvesting grain such as wheat, oats, rye, barley, Kafir com,

perfectly threshes it by removing any chaff still clinging to the grain after it has passed the primary threshmg cylinders, and then separating and cleaning the gram from the chaff, straw and refuse, and causlng the straw, chaif and refuse to be discharged from the rethreshing cylinder, and also providing means for conducting the cleaned grain from the rethreshing cylinder to any suitable receptacle. I

In the accompanying drawings, Figure 1 is a view in side elevation of the machine, with a portion of the casing broken away; Fig. 2 is a top plan view of the thresher with a portion of the casing broken away; Fig. 3 is a front elevation of the thresher with a portion of the casing broken away; Fig. 4 IS an enlarged detail sectional view of the casing, showing one of the threshing cylinders; Fig. 5 is a detail sectional View showing the. interior of the rethreshing chamber; Fig. 6 isa perspective view of'a portion of the casing disclosing a portion of the threshing chamber broken away to show the threshing cylinders; and Fig. 7 is a view in elevation of one of the threshing cylinders.

A, represents the frame of the forward truck, to which.an axle 1 is connected, and upon which wheels 2, 2, are rotatably mounted. The frame 3 of the rear truck is provided with a wheel 4 which is connected thereto by a yoke 5, the shank of which yoke is provided with a worm wheel 6. A crank shaft 7 is mounted upon the frame and is provided with a worm gear thereon, which engine 11 and connected to the forward end :of the frame A are vertical angle iron uprights 12, 12,which are braced to the frame by means of braces 13. J ournaled'at the upper ends of the uprights is a shaft 14, upon which are-mounted winding drums 15. The

threshing casing B is provided with" rollers 16, 16, carried in brackets 17, the rollers being received against the angle iron uprights 12. Ropes or cables 18 are connected to the casing B and to the winding drums 15 for supporting the casing upon the frame A and allowing the casing to be raised and lowered upon the rotation of the shaft, whereby the cables or ropes are wound or unwound on the drums 15. A worm wheel 19 is mounted upon the shaft 14, which meshes with the worm 20, carried by the shaft 21, which is supported by the reach 10 and post 22 on the rear truck frame'3. A crank 23 is connected to the shaft 21 for'rotating the shaft for causing the shaft 14 to rotate for raising and lowering the casing B.

J ournaled in the lower portion of the easing B are vertical cylinders 24 which are provided with teeth 25 formed spirally upon the outer surface of the cylinder. The forward end of the casing is provided with V-shaped projections 26 forming dividers for separating the stalks or straw so that, it will be fed through the openings 27 formed in the forward end or baseof the casing,

so that the-straw will come in contact orbe brought into a posit on so that the fingers or teeth 25 will come in contact with the straw and knock or brush the grain thereing orslot 27, to prevent the stalks or straws from being broken as the enter the housing or chamber 0 during t e removal of the grain from the stalks or straw. A guard 29 extends along the forward edge of the dividers and the function of thls guard rail chamber C for causing the grain to be delivered obliquely into the chamber or housing instead of driving the grain straight back. In this way, the grain is distributed into the housing in such a manner that it can be taken up by the conveyer 31, which travels lengthwise of the chamber and travels upwardto the rethreshing chamber D where the grain is discharged for the rethreshing operation.

The chamber D is located above the chamber C, and conduits 32 are provided whereby the endless conveyor 31 travels for carrying the grain from the chamber C to the rethreshing chamber D.- A rethreshing cylinder 33 is journaled in the chamber D and is provided with curved teeth 34. Thecurved or concave bottom 35 is located beneath and along one side of the horizontally journaled cylinder 33, and is provided with curved teeth 36, which extend in an opposite direction to the teeth of the cylinder 33. As the grain is discharged from the conveyer into the chamber D, it Will come in contact with the rotating cylinder 33, and

the grain will be acted upon by the teeth of the concavelbottom and cylinder, whereby all chafl' and straw will be broken therefrom and will be discharged onto the straw rack 37. The straw rack is mounted upon levers 38 and 39 which are pivotally connected to the casing B of the chamber D.

The rack 37 is composed of the usual form of slats and located below the rack is a vibrating riddle or screen 39' which is also connected to the levers 38 and 39. After the grain, chaff and straw are discharged from the concave 35, they will be received upon the rack 37, and the chaff and straw to a great extent will be discharged at the lower end of the vibrating rack 37, while the grain and a certain amount of the chaff and dust will be discharged onto the vibrating riddle or screen39', and eventually fall to the bottom 40 of the chamber D. The fan 41, journaled in the chamber, causes a blast of air to be driven across the bottom 40 and through the screen and rack, so that 'the chaff, straw and dust is blown from the chamber and the grain will travel down the inclined surface of the bottom 40 to the screw conveyer or auger 42, where it will be discharged from the chamber.

A telescoping shaft 43 is connected to the engine shaft by means of a universal joint 44. A shaft 45 is mounted upon the casing B, to which shaft the shaft 43 is connected by a universal joint 46. A pulley 47 is connected to the shaft 45, and passing around the pulley is a cable 48 which passes around pulleys 49 on the shafts 50 of the cylinders 24, whereby motion is transmitted to the cylinders. Idlers 51 are mounted upon the top of the chamber C intermediate of the pulleys 49 of the cylinders 24, so that the cable 48 will pass around the pulleys of the cylinder,

thence around an idler, and'thence around thepulley of another cylinder, whereby the several cylinders will all rotate in the same direction. A pulley 52 is mounted upon the shaft 45, around which a belt 53 passes, and thence around the pulley 54 on the shaft of the rethreshing cylinder 33. A pulley'55 is mounted upon the shaft 56, which shaft car:

ries sprocket wheels 57, the sprocket wheels engaging the chains of the belt or-conveyer 31, whereby upon the rotation of the pulley the conveyer is caused to move. A pulley 58 is mounted on the shaft 45, and around the pulley 58 and pulley 55 a belt 59 passes for transmitting motion for causing the endless conveyer to travel.v A crank shaft 60 mounted on the casing B has connected thereto an end of a lever 63, which lever 63 is connected to the vibrating rack and screen. The crank shaft 60 and the auger or screw conveyer 42, are driven by means of a belt 61 from the shaft of the fan 41, the fan receiving its. power A by a belt 64 which is driven by the shaft 45.

A clutch lever 65 is pivotally connected to the frame A and engages a clutch on the engine shaft, whereby the engine is controlled.

A rod 66 is connected to the lever 65, and

is connected to a lever 67, which is provided with a ratchet 68 for engaging the ratchet segment 69 for controlling the movement or operation of the engine.

From the foregoing it will be seen that by i this lnvention we have provided a series of vertical cylinders for threshing grain from the straw or stalk, as it stands in the field, and that the cylinders are capable of being raised and lowered to suit the different heights of the standing grain, and further, in the provision of an endless conveyor for conveying the threshed grain to a rethreshing cylinder, where the grain is cleaned and discharged onto a cleaning device for the removal of the chaff and other matter from the grain, and separating them by the vibration of the cleaning device, and the blast of air, and then conducting the grain from the rethreshing cylinder.

The invention further consists in the idea of connecting the rethreshing cylinder with thethreshing chamber, so that when the threshing chamber is moved, the other chamher is moved, and the movement of the threshing chamber in no wise affects the operation of the rethreshing chamber, as the conveyer is connected to both and continues to operate at all times when the cylinders in the threshing chamber are operating.

Another feature is in the fact that the 130,

raising and lowering features are controlled entlrely from the drivers seat and the ried by the cylinders for beating the grain from the standing stalks, and forcing the grain into the casing and means cooperating with the cylinders in removing the grain from'the stalks.
